Application filed May 18, 19 16, Serial No. 98,322.

To all whom it may concern:

Be it known that I, JOHN C. Moong'a citizen of the United States,residing at the city of St. Louis, State of Missouri have in- Vented acertain new and useful improve ment in Pipe-Assembling Machines, ofwhich the following is a full, clear, and exact description, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 is a side elevationalview of my improved pipe assembling machine.

Fig. 2 is a sectionalview on line 2-2 of Fig. 1.

Fig. 3 is a detail View of the pipes in their assembled relation.

Fig; i is a longitudinal sectional view through one form ofassemblingchuck.

Fig. 5 is an end elevational view of the assembling chuck shown in Fig.4.

Fig. 7 is asectional' view on line 77 of Fig. 6:

Fig. 8 is a longitudinal sectional view through another form of chuck.

Fig. 9 is'an end .elcvational view of the form of chuck shown in Fig. 8.

Fig.10is,a plan view of the feed table for use in connection with'thechuck shown in Fig. 11 is a sectional vlew on line 1l1 l ting-1 AThisinvention relates to a new and u'sefu'l improvement in pipeassembling machines,

the object beingto construct. a machine which is simple and cheap andone which. is easily and quickly operated.

The mach'ne shown the accompanying drawingsisfde'signed especially foruse in i constituting the'cylinders of a pneumatic pump, into" asuitable base,

the passes assembled being shown'in -Fig.

will be moved outwardly on shaft 3;=*and when lever 13 is depressed,collar 6 will be moved inwardly on said shaft. The outer end of collar 6is formed with a" cone-shaped 3, but it is obvious that the principlesof p the presentinventionjmay ,be employed in L I assemblingotherfstructures,whether theybe p'ipes or rods jd s. hows in Fi 50 Thepump base and .cylin- '3. lln sses t pa to be ssm l di y' he P sepreatus, consist ofjabase casting "Ayha'vi'ng I suitable bossesextendingjupon nsnpper side into which refthread d I p H and short pipeB and a r'ela't e1y1a1rg'e and of c arse eser iti' are in relativelysear screwed threads formed on the respective parts properly engage, butthis hand operation is not only tedious, but unsatisfactory, in that itis costly. To seat the ipes properly in the base in hand-assemb ing, thepipe is clamped in a vise and then the base screwed on. Sometimes it isdifiicult to find a thread and in consequence the bosses on the base arereamed out as shown at a in Figs. 1 and 8 so as to provide a smooth,unthreaded entering mouth for the threaded end of the pipe, the threadsin the boss being out near the bottom thereof. The present invention isnot concerned with the threading of the pipes or the reaming of thebosses as these operations are presumed to have been performed beforethe parts are in readiness for assemblage. 'The parts so formed areplaced within convenient reach of the operators, preferably twomachines, one for the smaller pipe and one for the larger pipe, beingarranged side by side, one operator, after assembling the small pipe onthe base, passing such assembled parts to the next operator for thepurpose of en- 1:gbling him to assemble the large pipe on the ase.

In thedrawings, 1 indicates a bench or table. on which is mounted acasting 2 forming bearings in which is mounted a shaft 3 driven by meansof a belt 4 passing around a pulley 5 on said shaft. Mounted to slidelengthwise upon and rotatewith shaft 3 is a collar ,6 in which is formeda peripheral groove and loosely mounted therein is arin'g 7 the sameserving as a gimbal bearing for said collar. (See Figli), This ring 7pivotally connected to the bifurcated end of a leve'r 8', the same beingpivoted at 9 to the casting 2 and the opposite ends of the lowerfacebriwithf which cooperate the inner ends for clamping-leyers' l4,saidjlevers being piv- ','"oted"ina support 15' threaded on shaft and lcked in position thereupon by a jam flfl'? is a centering fpin,preferably pointed its outer end, forming acontinuation 50f "shaft Sandwhoseexternal diameter is such as to fit within the pipe B. The outerends of levers 14 are provided "Width. @HYfid clamping jaws (see Fig. 5)which are designed to grip the end of pipe B when footlever 12 isdepressed.

The sinnerends of .the clamping .jaws 1a are preferably provided withrods con; nected by retraotile springs 19'wherebywhen thase a fi-v ssl vw fdlv Q t atha blage iqon istsi i We uid i e m i i 2Q supn nte i s tabldist n e eb il h W qngbe eh lvb tws i t ie .$2251 iembes slidinglam pertes a; hede ete w t h e pe ian we srend a m-flit. ahg eqre seat n tdimer; a e qm mir th -abas ssast n ed es Big-5,7,) rsaifilflhesl pl teals iserryin 5 he gainhi hr-et ififi ab yn tend vb r ies u ses me i w291 $0, as t isoipere eawi hri tql b qks, 2 projecting upwardly from thelnner end s g sa d. gamma-membe s 7 32a a e s e hereZQmay hae ee ed Qbye 231 f?
